When Riteish and Genelia Deshmukh entered the house they lived in firstly, they had to break a window glass. The next time they entered, the broken glass was replaced with a very obvious new one. They had no money to eat, no way they could have repaired the glass themselves.
The owner of the house Riteish and Genelia lived in was not revealed throughout the movie. They entered a new house, met no one there, lived there.
